First time accepted submitter nani popoki writes "Skipping a good night's sleep can cause brain damage according to a new study. From the article: 'Are you a truck driver or shift worker planning to catch up on some sleep this weekend? Cramming in extra hours of shut-eye may not make up for those lost pulling all-nighters, new research indicates. The damage may already be done — brain damage, that is, said neuroscientist Sigrid Veasey from the University of Pennsylvania. The widely held idea that you can pay back a sizeable "sleep debt" with long naps later on seems to be a myth, she said in a study published this week in the Journal of Neuroscience. Long-term sleep deprivation saps the brain of power even after days of recovery sleep, Veasey said. And that could be a sign of lasting brain injury.'"
